Characteristics of patients with fluid extravasation during retrograde ureteroscopic holmium laser lithotripsy for renal calculi

To explore the risk factors of fluid extravasation during retrograde ureteroscopic holmium laser lithotripsy for renal calculi. Three hundred and twenty-seven patients with renal calculi ranging 10 to 20 mm received retrograde ureteroscopic holmium laser lithotripsy at Renmin Hospital of Wuhan University, Wuhan, China from January 2004 to December 2010. The clinical records were reviewed, and the correlation was studied between various clinical factors and fluid extravasation complications during operation. The clinical factors to be tested included patients' gender and age [<30, 30-50, and >50 years], hydronephrosis degree, previous intervention for renal calculi [none, shock-wave lithotripsy, and open surgery], upper urinary tract infection, ureteral access sheath placement, and procedure duration [<60, 60-120, and >120 mins]. The data were processed by SPSS Version 16.0 statistical software, x[2] test, and binary logistic regression were used for analysis. Fluid extravasation complications appeared in 35 patients. Patients` gender, age, and hydronephrosis degree were irrelevant to the occurrence of fluid extravasation, while having previous open surgery for renal calculi, without ureteral access sheath placement, upper urinary tract infection, and long procedure duration were all responsible for higher incidence of the complications. Reasonable selection of patients, effective control of upper urinary tract infection, routine ureteral access sheath placement, and controlling procedure duration help to decrease the incidence of fluid extravasation complications in retrograde ureteroscopic holmium laser lithotripsy for renal calculi

Treatment of buried penis in children with fixation at the dartos coat of penis through prepubic route / 中华男科学杂志

<p><b>OBJECTIVE</b>To observe the long-time results of the treatment of buried penis with fixation at the base of penis through pre-pubic route.</p><p><b>METHODS</b>From Aug 2002 to Dec 2003, the procedure was performed in 34 children without penile skin insufficiency. The major technique involved the release of hided penis shaft by partly shearing suspensory ligament, fixating the bucks fascia and tunica albuginea at 3 and 9 o'clock positions with the subcutaneous penile skin at the base of penis just under the pubic symphysis.</p><p><b>RESULTS</b>Twenty-one patients have been reviewed over one year with satisfactory appearance. Thirteen patients were lost to follow-up. No recurrence happened in our group.</p><p><b>CONCLUSION</b>We compare this technique with major treatment methods for buried penis in children at present, and we conclude this technique is a reasonable, simplified and aesthetical method for the treatment of buried penis in children.</p>

The long-term results of radical nephrectomy for small renal carcinoma / 中华泌尿外科杂志

Objective To investigate the long-term follow-up results of patients treated with radical nephrectomy for small renal carcinoma.Methods Between January 1992 and June 2004,a total of 56 pa- tients(41 men and 15 women;mean age,54 years;age range,19-71 years)underwent radical nephrectomy for small renal carcinoma.The clinical data and long-term follow-up results of the 56 cases were analyzed ret- rospectively.All the patients were followed by questionnaire;and the 5-and 10-year survival rates were calcu- lated by Kaplan-Meier method.Results None of the patients was found to have metastasis preoperatively. Postoperative pathology showed renal clear cell carcinoma in 44 cases,granular cell carcinoma in 7,and mixed cell carcinoma in 5.Among these cases,ipsilateral adrenal metastasis was found in 1 case,local lymph- aden metastasis in 2,and perirenal fat metastasis in 4.Postoperatively,49 of the 56 patients(87.5%)were followed for 11-155 months with a mean of 71 months.The 5-and 10-year survival rates were 81.7% and 66.9%,respectively.Five patients died of metastasis from renal carcinoma.Conclusions Radical ne- phrectomy for small renal carcinoma has favorable long-term effects,therefore it is an optimal surgical proce- dure for small renal carcinoma.
